iPhone 12 Won’t Connect To WiFi After iOS 14.3 Update

In this troubleshooting guide, we will show you what to do if your iPhone 12 won’t connect to your Wi-Fi network after the recent iOS 14.3 update. Network issues like this may occur every now and then, but most of the time, they’re not really that serious. Continue reading to learn more about it and how to fix it. 

A powerful smartphone like the iPhone 12 shouldn’t have problems connecting to your WiFi network. That’s why when a problem like that occurs, there is always a possibility that it’s an issue with your network device. However, you have to troubleshoot your devices to be able to know the reason why it occurs. Here’s what you should do: 

First solution: Restart  your router and your iPhone

Before anything else, the first thing you have to do is to refresh the memory of your router and your iPhone. There’s always the possibility that it’s just due to a pretty minor glitch in the systems of your devices. Here’s how you do it: 

  1. Unplug the router from the outlet, or simply disconnect the power cord from the main unit. 
  2. Leave it without power for a minute or two. 
  3. While waiting, quickly press and release the Volume Up and the Volume Down buttons. 
  4. Immediately after that, press and hold the Power key for 10 seconds. This will trigger your device to shut down and power back up. 
  5. Once the Apple logo shows, release the power key and allow it to complete the boot process. 
  6. Now plug your router back into the outlet, or reconnect the power cord to the main unit. 

Wait for your devices to become active, and then let your iPhone reconnect to the network. 

Second solution: Forget the network and reconnect to it

If restarting your router and iPhone cannot fix the problem, then the next thing you have to do is to re-establish the connection between them. Basically, what you need to do is delete the current connection and let your iPhone reconnect to the network. Here’s how you do that: 

  1. Launch the Settings app on your iPhone. 
  2. Tap Wi-Fi. 
  3. Tap the Info icon next to your network. 
  4. Tap Forget this Network, and then tap Forget to confirm. 
  5. Once your iPhone has detected your network, tap on it. 
  6. Enter your password and then tap Join to reconnect. 

Most of the time, this solution will fix problems like this. However, if the issue persists, then move on to the next solution. 

Third solution: Reset the network settings of your device

After doing the first two solutions and your iPhone 12 is still not able to connect to your network, then it’s time to reset the network services. Doing so will bring the network settings back to their default configuration. It’s also one of the effective solutions to this problem. Here’s how it’s done: 

  1. From the Home screen, tap Settings. 
  2. Tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Touch Reset Network Settings. 
  5. If prompted, enter your security lock. 
  6. Tap Reset Network Settings at the bottom of the screen. 

Your iPhone will reboot after this, once it has finished rebooting, try to see if your iPhone 12 can now connect to your Wi-Fi network. 

Fourth solution: Factory reset your phone

At this point, if the problem is still not fixed, then what you have to do next is the factory reset. A reset will be able to fix an issue like this. However, make sure to back up your important files and data as they will be deleted. Once you’re ready, follow these steps to reset your phone: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Tap Erase All Contents and Settings. 
  5. Tap Erase Now. 
  6. If prompted, enter your security lock. 
  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed.  
  9. Now enter your Apple ID password, and then tap Erase to proceed with the reset. 
  10. Wait until your iPhone has finished the reset, and then set it up as a new device. 

It should be able to connect to your Wi-fi network now.
